Precautions
WARNING: Use of controls, adjustments, or procedures other than those specified in this
documentation may result in exposure to shock, electrical hazards, and/or mechanical hazards.
Read and follow these precautions when connecting and using your computer monitor:
PRECAUTIONS
Do not use the monitor near water, e.g. near a bathtub, washbowl, kitchen sink, laundry tub,
swimming pool or in a wet basement.
Do not place the monitor on an unstable cart, stand, or table. If the monitor falls, it can injure a
person and cause serious damage to the appliance. Use only a cart or stand recommended by the
manufacturer or sold with the monitor. If you mount the monitor on a wall or shelf, use a mounting
kit approved by the manufacturer and follow the kit instructions.
Slots and openings in the back and bottom of the cabinet are provided for ventilation. To ensure
reliable operation of the monitor and to protect it from overheating, be sure these openings are not
blocked or covered. Do not place the monitor on a bed, sofa, rug, or similar surface. Do not place
the monitor near or over a radiator or heat register. Do not place the monitor in a bookcase or
cabinet unless proper ventilation is provided.
The monitor should be operated only from the type of power source indicated on the label. If you
are not sure of the type of power supplied to your home, consult your dealer or local power
company.
The monitor is equipped with a three-pronged grounded plug, a plug with a third (grounding) pin.
This plug will fit only into a grounded power outlet as a safety feature. If your outlet does not
accommodate the three-wire plug, have an electrician install the correct outlet, or use an adapter to
ground the appliance safely. Do not defeat the safety purpose of the grounded plug.
Unplug the unit during a lightning storm or when it will not be used for long periods of time. This will
protect the monitor from damage due to power surges.
Do not overload power strips and extension cords. Overloading can result in fire or electric shock.
Never push any object into the slot on the monitor cabinet. It could short circuit parts causing a fire
or electric shock. Never spill liquids on the monitor.
Do not attempt to service the monitor yourself; opening or removing covers can expose you to
dangerous voltages and other hazards. Please refer all servicing to qualified service personnel.

appropriate configured receptacles marked between 100 - 240V AC, Min. 5A.
The wall socket shall be installed near the equipment and shall be easily accessible.
For use only with the attached power adapter (Output 12Vdc) which have UL,CSA listed
license(Only for monitors with power adapter).
Please make sure to clean the cabinet regularly with the provided cloth , you can use soft-cleanser

DCB Adjustment
What is DCB?
Dynamic Color Boost (DCB) is an advanced color adjustment technology. Through analyzing RGB signals, DCB creates
more vivid and natural images to suit various color environment needs. DCB has two types of color enhancers: “Color
- 10 -
Boost” and “Picture Boost” .
DCC: Dynamic color control
ICM: Intelligent color management
1) How to use Color Boost?
Five color-enhancement settings: To accommodate various display needs, Color Boost also offers 5 different color
enhancement modes: Full Enhance, Natural Skin, Green Field, Sky Blue, and Auto-Detect. Please go to the fourth icon
labeled “Color Boost” in the OSD menu and select one of the five settings you desire to be turned on.
Full Enhance: When "Full Enhance" is turned on, the color saturation of the entire screen is fully enriched, thus all colors
become more vibrant.
Nature Skin: When "Natural Skin" is turned on, the red and yellow colors are enriched automatically, thus presents
human skin with more natural and truer colors. "Natural Skin" setting is ideal for viewing human portrait and detailed skin
- 11 -
texture.
Green Field: When "Green Field" is turned on, the green color is enriched so that football field and mountain landscape
would look more natural and fresh. “Green Field” setting is ideal for watching mountain scenery and outdoor sports.
Sky Blue: When"Sky Blue" is turned on, the color blue is being fine-tuned so that the sky or ocean landscape will look
more vivid and in-depth. "Sky Blue" setting is ideal for viewing sky and ocean images.
- 12 -
Auto Detect: When “Auto Detect” is turned on, every pigment will be detected and self-adjusted to render a lively
picture.
Demo: Screen divided into two for demonstration purposes.
2) How to use Picture Boost?
Users can change the color settings of a self-selected zone on the screen. The size and position of the selected zone can
also be adjusted. "Picture Boost" is located in the fifth icon labeled "Picture Boost" in the OSD menu. Turn on "Bright
Frame" to select a zone on the screen to be enhanced. Please note when adjust or turn on any one of the DCB features,
the rest of color settings including DCR will be disabled or return to default.

Disclaimer: DCB aftereffects are subject to the resolution and quality of the display content, hence may look different than
the above illustrations.
DCR Adjustment
What is DCR?
Dynamic Contrast Ratio (DCR) auto adjusts the brightness of the screen so users can see the darker areas of the
displayed content in more depths. By increasing the darkness of the dark areas and the brightness of the bright areas,
contrast ratio is uplifted to exceed 10,000:1. DCR value varies subject to the original CR values of the LCD module. The
higher the original CR, the higher DCR can be achieved. DCR is great for watching movie or video contents.
How to Use DCR?
Go to the first OSD icon labeled "Luminance", turn on or off DCR as desires. DCR boosts the contrasts between lightness
& darkness and enables the viewer to see more layers and details of the picture, especially in the darker areas. Please
note when DCR is on, DCB will be disabled.
